Azteca: Aztec-Inspired Bean Soup Recipe for a Hearty Vegetarian Dish

Azteca is an Aztec-inspired bean soup that uses tinned corn and beans for a fast, filling meal. The source recipe comes from Bob Uhl’s "Azteca" on his bachelor recipes site. It is inspired in the loosest sense and is not historical. This version keeps the same simple method and clear flavour profile.

This vegan bean soup cooks in about 30 minutes and suits a beginner skill level. It uses pantry staples, so it fits busy weeknights. It is also naturally gluten-free, with no wheat-based items in the pot. The heat comes from dried pequin chillies, balanced by sweet corn and soft beans.

Use standard tins, then measure water with the empty tins for the same result as the source. Drain the corn and beans to avoid a salty broth. Keep the onion and garlic very finely minced so they soften fast. Adjust salt and pepper at the end, since tinned foods vary.

• 1 tin corn, drained (about 400 g tin; about 2 cups / 480 ml kernels)
• 1 tin kidney beans, drained and rinsed (about 400 g tin; about 2 cups / 480 ml beans)
• 1 tin black beans, drained and rinsed (about 400 g tin; about 2 cups / 480 ml beans)
• 1/2 medium onion, finely minced (about 75 g; about 1/2 cup / 120 ml)
• 4 garlic cloves, finely minced (about 12–16 g; about 1 tablespoon)
• 6 dried pequin chillies, chopped (about 3–5 g; adjust to taste)
• Mustard seeds, to taste (start with 1/2 teaspoon)
• Salt, to taste (start with 1/2 teaspoon)
• Freshly ground black pepper, to taste (start with 1/4 teaspoon)
• Water: 3 tinfuls (use the empty 400 g tin; about 1.2 litres total)

Equipment

This bean and corn soup needs only basic tools. Use a medium pot so the soup boils without spilling. A lid helps the onion cook faster, but you can cook uncovered and stir more often. Chop the dried chillies carefully, since the pieces can be sharp and hot.

• Medium pot (3–4 litre capacity)
• Chopping board and knife
• Can opener
• Measuring spoon set
• Wooden spoon or ladle

Step-by-step procedure

The original method is simple: mix, add water, and boil until done. Here, "done" means the onion and garlic taste cooked, and the flavours blend. Since the beans are already cooked in tins, the main cooking time is for the aromatics and chillies to soften in the broth.

1. Put the drained corn, kidney beans, and black beans into a medium pot.
2. Add the minced onion, minced garlic, and chopped dried pequin chillies.
3. Add mustard seeds, salt, and black pepper. Start with small amounts.
4. Fill one empty tin with water. Pour it into the pot. Repeat twice more (3 tins total).
5. Stir well and bring the soup to a boil on medium-high heat.
6. Lower the heat to a steady simmer. Cook for 15–20 minutes, stirring at times.
7. Taste and adjust salt, pepper, mustard seeds, or chilli heat as needed.

Notes, tips, and variations from the source

The source notes a more historically accurate direction, but also states this dish is not historical as written. If you want that closer style, swap pinto beans in for kidney beans, use Mexican green onions, and leave out garlic and mustard seeds. It also suggests using powdered chilli pepper instead of black pepper.

Serving and storage

Serve Azteca bean soup hot as a side dish or a light main. It is thick, so it can also work as a bowl meal with extra water added at reheat. Cool leftovers fast and store them in a covered container in the fridge. Reheat to a full boil, then simmer for a few minutes.

Nutritional values (estimated)

These values are estimates for one quarter of the pot, based on typical drained tinned corn and beans, plus onion and garlic. Brands differ, and salt added at cooking changes sodium. For accurate numbers, check your tin labels and measure the exact drained weights you use.
